Method 1
Make a copy of the gray test chart (UKOG-0162FCZZ) and a copy
of the servicing color test chart (UKOG-0326FCZZ/UKOG-
0326FC11), and check that they are proper.

color copy mode
To check the copy color balance and density, use the gray test
chart (UKOG-0162FCZZ) and the servicing color test chart

In addition, all the color balance adjustments in the user adjust-
ment mode must be set to the default (center).
